专利说明:

 . . one . The invention relates to chemical plant protection agents, specifically to a herbicidal agent based on diurethane derivatives. A herbicidal agent based on 2- & pure-butyl-4, b-dinitrophenrel 1 is known. The closest in chemical structure to the invention is a herbicide based on 1 -methyl- 3- (s-3-methylphenylcarbamoyloxy) -phenyl-carbam 12. However, these herbicides around f give insufficient activity at low concentrations. obtaining new herbicidal agents possessing their own high herbicidal activity. This goal is achieved by using compounds of the general formula as diurethane derivatives (I "OCzHj de R - hydrogen or normal alkyl; secondary or tertiary butyl; tertiary amyl; allyl; prop argyl; 1-methylpropargyl chloroisopropyl; chlorine-glr &t-butyl; 1-chloromethyl-2-methoxy t. 2, b-dimethyl- and 3,5-dimethylcyclohexyyl; 1-methyl cyclopentyl; norbornyl; phenyl; 2-ethyl, 2-isopropyl, 3-methyl-, 3-etyl-j 4-fluoro-4-chloro , 4-methyl-, 4-isopropyl-, 2-3-dimethyl-, 2,5-dimethyl-, 2,6-dimethyl-, 3,4-, tetramethyl-, 3,5-diethyl-, 2-methyl -5-isopropyl-, 3-methyl-4-chloro, 2-methyl-6-isopropyl- and 3-methyl g 5-ethyl-phenyl; benzyl; or, the radical form / LY (II). , GTG MN-BOO 3 methyl; ethyl; isopropyl; tertiary butyl, allyl, propargyl, or phenyl; Chestye 0.1-95 wt.%. measures. To a solution of parts of a complex 4-chlorophenyl 3-aminophenyl) -carbamic 125 parts by weight tetrahydrofuran Table. 14 gives the herbicide of the compound of the formula jT-dOOF × YAN-COOKD when processing before or after the greenhouse; Table 15 shows the selection of the effect of the compound of the formula O RI after the shoot in the greenhouse. In Table 1b, the selection of a compound of the formula O RI Ej-0- (JN NdO-Bj with weeds in cultivated plants upon treatment after germination in t is given. Table 17 gives a selective outside compound of the formula I jf Bg-O-CJ-N seedling treatment in a teppice. Table 18 gives a selective effect of a compound of the formula .. BUT I G -NCO-RJ with weeds in cultivated plants when processed after a shoot in warming Table 19 gives the effect of urethane formulas R-O-C- and l Weed control in wheat when processed after emergence in warming Table 20 gives a herbicidal action of diurethanes of the formula O RI .r-tch
